Differentiation of Plant Tissues: An Introduction
FAQs on Difference Between Differentiation and Dedifferentiation
1. What are the characteristics of Dedifferentiation?
Dedifferentiation is the process by which differentiated cells in a specific area of the plant body recover their ability to divide. It enables the plant to create new cells in a specific area. Dedifferentiation of differentiated cells therefore typically occurs before significant physiologic or structural change. The functional forms of the cells return to their early developmental stages during dedifferentiation. Dedifferentiated cells, therefore, function as many types of meristematic tissue in plants, such as the interfascicular vascular cambium, cork cambium, and wound meristem.
2. What are the characteristics of Redifferentiation?
Redifferentiation is the loss of a differentiated cell's ability to divide after it has regained it. It enables functionally specialized cells to operate as differentiated cells inside the plant body. The treated differentiated cells often return to the redifferentiated state after dedifferentiating the plant body to prepare it for physiological or structural change and fulfill a specified role.
3. Give differentiation dedifferentiation and redifferentiation examples.
Dedifferentiation is exemplified by the creation of the interfascicular cambium and cork cambium from completely differentiated parenchyma cells, whereas redifferentiation is exemplified by the specialization of vascular cambium into the secondary xylem and phloem. For instance, after cell division, the dedifferentiated vascular cambium redifferentiates into the secondary xylem and phloem. However, the cells in the secondary xylem and secondary phloem are unable to undergo additional cell division, and once they have reached maturity, they carry out tasks like conducting food and water while preserving the structural integrity of the plant.
